Comparator output is sampled on

which is then resampled on an
interval determined by C0[FPR] to
generate COUT.

Windowed/Filtered mode
Comparator output is sampled on
every rising bus clock edge when
SAMPLE=1 to generate COUTA,
which is then resampled and filtered
to generate COUT.
All other combinations of C0[EN], C0[WE], C0[SE], C0[FILTER_CNT], and C0[FPR] are illegal.
For cases where a comparator is used to drive a fault input, for example, for a motor-
control module such as FTM, it must be configured to operate in Continuous mode so
that an external fault can immediately pass through the comparator to the target fault
circuitry.
Note
Filtering and sampling settings must be changed only after
setting C0[SE]=0, C0[FPR] =0 and C0[FILTER_CNT]=0x00.
This resets the filter to a known state.
